This is after the helicopter chase when you close your eyes. It seems like a lot of people, per the 'Discussion Boards' via Steam, are having this issue as well. I do not think the trainer has any influence on this issue. Looks like it's a big bug. 8( Just thought I'd pass this along as I am having the same issue and going back to the beginning would suck. Good luck all.

Thanks for pointing this out. I'm having the same problem. Tried reloading older save without a trainer and still get this bug. Guess we'll have to wait for a patch.
